Ventilation and Combustion Air
Wall furnaces shall be installed in a location in which the facilities for
ventilation permit satisfactory combustion of gas and proper venting
under normal conditions. In buildings of conventional frame, brick, or
stone construction without tight storm windows and doors, infiltration
is normally adequate to provide air for combustion and draft hood dilu-
tion.
Where appliances are installed in confined and unconfined spaces
within a building, the building being of unusually tight construction, air
for combustion and ventilation must be obtained directly from outdoors
or from such spaces that freely communicate with the outdoors. Under
these conditions, the confined and unconfined spaces shall be provided
with two permanent openings, one near the top of the enclosure and one
near the bottom; each opening shall have a free area of not less than one
square inch (6.45cm
2
) per 2,000 BTU hr. (.6KW/H) of total input.
Qualified Installing Agency
Installation and replacement of gas piping, gas utilization equipment or
accessories and repair and servicing of equipment shall be performed
only by a qualified agency. The term “qualified agency” means any indi-
vidual, firm, corporation or company which either in person or through
a representative is engaged in and is responsible for (a) the installation
or replacement of gas piping or (b) the connection, installation, repair or
servicing of equipment, who is experienced in such work, familiar with
all precautions required and has complied with all the requirements of
the authority having jurisdiction.
The installation must conform with local codes or, in the absence of
local codes, with the National Fuel Gas Code, ANSI Z223.1/NFPA 54*
Natural Gas and Propane Installation Code, CSA B149.1.

Clearances
1. In selecting a location for installation , it is necessary to provide
adequate accessibility clearances for servicing and proper installa-
tion.
2. The FAW-55 can be attached to the wall or recessed into the wall up
to 4 inches (102mm) in depth.
3. The wall in which the furnace is recessed has (0) zero (0mm) clear-
ance to the furnace sides and top.
4. When using side discharge registers, SOR-1 or SOK-1, the furnace
cannot be recessed into the wall.
5. Clearance to sidewall or combustible material is 4 inches
(102mm).
6. Ceiling clearance is 7 1/2 inches (191mm)
7. Floor and rear wall clearance is (0) zero inches (0mm).
8. Clearance of 18 inches (457mm) is required to adjacent wall or com-
bustible material when flushed mounted SOR-1, side outlet register
is used.
Before Installing Consider The Following Venting
1. A chimney for residential-type or low-heat gas utilization equipment
shall extend at least 3 feet (914mm) above the highest point where it
passes through a roof of a building and at least 2 feet (610mm) higher
than any portion of building within a horizontal distance of 10 feet
(3m).
2. This furnace must not be connected to a chimney flue serving a
separate solid-fuel burning appliance.
3. Uninsulated Single-Wall Metal Pipe shall not be used outdoors in
cold climates for venting gas utilization equipment.
4. Attention! This Fan Type Vented Wall Furnace is equipped with a
vent safety switch. In the event of spillage of flue products due to
improper venting the vent safety switch will open, which results in

Listed gas vent equipment.
Installing Optional Side Outlets
Side outlet register, SOR-1 may be installed on one or both sides of the
furnace at the required clearances of 18 inches (457mm) to adjacent wall
or combustible material as shown in Figure 2.
1. Locate and cut the 5 1/2” (140mm) square opening in the cabinet side
using the template from the kit, exposing the inner liner knock-out.
2. Remove the knock-out.
3. Place the register on the 5 1/2” (140mm) opening with the louvers
set for the desired direction and mark the mounting holes using the
register as a template.
4. Drill two (2) 1/8” (3mm) diameter holes in cabinet side and fasten the
register in place with two (2) #10 x 1” (25mm) screws provided.
Side outlet kit, 10” (254mm) boot assembly with register, SOK-1 for warm
air discharge into an adjoining room may be installed on either side of the
furnace at the required clearance of 4 inches (102mm) to adjacent wall as
shown in Figure 3A.
1. Locate and cut the 5 1/2” (140mm) square opening in the cabinet side
using the template from the kit, exposing the inner liner knock-out.
2. Remove the knock-out.
3. Using the inner and outer boots as hole templates, mark and drill (8)
1/8” (3mm) diameter holes in the inner liner and cabinet side.
4. Using Figure 3A locate and cut a 6 3/4” (171mm) square opening
